Answer:
x = 6 + 3√10
Step-by-step explanation:
Since this is an unfactorable expression, we need to apply the Quadratic Formula, <em>-</em><em>b</em><em> </em><em>±</em><em> </em><em>√</em><em>b</em><em>²</em><em> </em><em>-</em><em> </em><em>4ac</em><em>\</em><em>2a</em><em> </em>[radical wrapped around <em>b</em><em>²</em><em> </em><em>-</em><em> </em><em>4ac</em>]. Evaluate, then you will end up with the answer above.

Answer:
16 y.o
Step-by-step explanation:
say rebecca = x
therefore, cynthia = 6x
when rebecca ages 6 years (x+6), cynthia will be 3(x+6) years old
since cynthia's original age + 6 will be equal to the new expression of her age after 6 years
3x + 18 = 6x + 6
18 = 3x + 6
3x = 12
x = 4
as cynthia = x + 6 (NOTE: AT THE BEGINNING) her original age was 10.
however after 6 years she's 16
7. tan º = o/a
tan 24 = 24/x
24*tan 24 = x
x= 53.904
8. tan º =o/a
tan 24= 24/x
24/tan 24 = x
x= 53.904
9. cos º = a/h
cos 34 = x/46
46*cos 34 = x
x=38.135
